Both has a perfect mix of design and function, including interesting mechanisms and excellent look.
The first one The rocking Escalator "controlled by a pirate captain of the space Is a very cool idea mixing the rocking "stairs" an a tilting bed, this combined mechanism is fed by a pump system driven by an independent motor. Nice example of high grade of innovation in the mechanisms and not forgetting decoration and aesthetics in GBC development.
The second has TLOTR theme and will be very popular among the lovers of this theme, in this case the level of detail in the scenery is very high like the best vignettes had, representing moments of the book ( or the films)it has lots of TLOTR minifigs, PF lights and also includes spiral lift and "stairs" mechanisms perfectly integrates in the diorama that the module is itself.
It is truly a masterpiece
